Abstract
The tetrahydrocannabinol (THC) contents of 220 samples of fresh illicit Cannabis products seized on entry into the UK of Great Britain and Northern Ireland over the period 1979-1981 were determined by gas chromatography. During that period there was a general increase in the quality of both cannabis and cannabis resin, but with wide variations in THC contents both within and between countries. Some very high quality samples of cannabis, cannabis resin and cannabis oil from the Indian sub-continent were analyzed. There have been considerable changes in the number of fresh samples from several countries, compared with the previous survey. Fresh cannabis oil samples were very rare during the period covered by this survey.
